Fix deprecation warnings from SASS

[andreslucena]

🎩 What? Why?

There are some deprecation warnings when building the assets that come from a change in SASS syntax:

DEPRECATION WARNING: Sass's behavior for declarations that appear after nested
rules will be changing to match the behavior specified by CSS in an upcoming
version. To keep the existing behavior, move the declaration above the nested
rule. To opt into the new behavior, wrap the declaration in `& {}`.

More info: https://sass-lang.com/d/mixed-decls

This PR fixes those error messages. The only deprecation warnings left are from tom-select, it was reported in this issue: orchidjs/tom-select#742

Testing

Run rm -rf public/decidim-packs/ ; bin/rails assets:precompile and see the output (before and after this patch)

♥️ Thank you!

Checked the pipeline output. The only deprecation warnings were related to tom-select.

@andreslucena , maybe we can set the type to fix, so that we can backport it to 0.29 ?
